Iptg red induction
WebIn the absence of induction of the lacUV5 promoter, little T7 RNA polymerase or target protein should be present and the cells should grow well. However, upon addition of an inducer, typically isopropyl-b-D-thiogalactoside (IPTG),1T7 RNA polymerase will be made and will 1046-5928/$ - see front matter.
